Women are given less dialogue in Hollywood films the older they get, according to a new study.

A survey of 2,000 movies by Polygraph found that women between the ages of 22 and 31 spoke 38% of all female dialogue. The figure fell to 31% for actors aged 32 to 41 and 20% for those aged 42 to 65.

By contrast, male actors got more lines the older they became, right up to the age of 65. Men aged 42 to 65 got more dialogue (39%) than those aged 32 to 41 (32%) or 22 to 31 (20%).

However, both sexes suffered once they hit 65, with male actors getting 5% of dialogue, and female actors just 3%.

Polygraph also found that women often struggled to win dialogue even in ostensibly female-led projects. In the Disney films Pocahontas and The Little Mermaid, men spoke at least 70% of dialogue, though more recent projects from the Mouse House (Frozen, The Incredibles and Into the Woods) had a more even gender spread. Inside Out, Maleficent and Alice in Wonderland had more female speakers.

In related news, the director of pioneering action movie Hardcore Henry has defended the film against accusations that the vast majority of its female cast members play prostitutes.

Last week, The Wrap’s Tim Molloy pointed out that 31 of the Go Pro-shot video game riff’s 45 female characters were sex workers. Responding on Twitter, Ilya Naishuller said he was being “nice” by handing each of his female stars a full credit rather than listing them merely as extras. Molloy later hit back, advising Naishuller to “own” his misogyny, adding: “You set out to make an adolescent dude fantasy, right?”

@TimAMolloy Grabbing at straws much?The list of brothel ladies would usually be clumped together as extras... (1/2)
